Simple way to setup ruby on linux

12 Jun 2023

What’s the problems though ?

So recently I had to utilize a way to setup ruby, required by a jekyll template of Hugo.
It was 3 year old setup.
Installed with package manager snap and apt.

Though packages were installed there were env related issues <- This is the main messup right here.

dependencies and env issues with ruby take much time to resolve.

What helped ?

RVM

RVM is the keeper though <3

It is called Ruby Version Manager, seems straightforward.

Steps to setup RVM:-

Execute the following shell commands

 sudo apt-get install software-properties-common -y
 sudo apt-add-repository -y ppa:rael-gc/rvm
 sudo apt-get update
 sudo apt-get install rvm -y
 sudo usermod -a -G rvm $USER
 echo 'source "/etc/profile.d/rvm.sh"' >> ~/.bashrc

Restart the shell that you are currently using (as we have added rvm.sh in it’s bashrc)
Use the rvm command to set things up. (If you followed the above steps the binary rvm should be in the right path)

How do you set things up using RVM ?

Install the specific version as follows:-

rvm install ruby-2.2.10

One beautiful thing about this is that you can install multiple versions of the ruby on the same vm.

On executing rvm --list we can see all the versions setup as follows:-
